1. The instrument consists of well logging, precise digital water level gauge, submersible pump, data acquisition and cΩontrol box. For automatic measurement of record runoff. This instrument c€onsists of 1 log, logging 2 (the instrument whose resoluti‍on is 0.1 L / min, the measurement accuracy is less than 1%, stable and reliab le performance is far better than other forms of runoff.). The co₽ntrol box is equipped with PC communication interfαace, and can be connected with the computer. Automatic plotting of runoff process curve frπom upper computer. This instrument can be used with JFZ-01 type digital gauge is used fo¶r automatically recording, and on the basis of precipitation runoff process curve, pr¶ecipitation process curve to calculate runoff criti♦cal rainfall (rainfall).
